(This was originally filmed as a custom video and has a slower build-up than my videos normally do - it's a very natural and real feeling slow increase of tension!) You're quietly watching porn in your living room, very late at night, when your sister walks past on her way to the kitchen and hears you! She sticks her head in the door and makes you jump, asking what it is you're watching in here... You quickly change the screen and tell her it was just a movie, but you can tell she's not buying it. She sits down on the couch as if she has no intention of leaving, and makes you own up to watching porn. When you finally admit it she laughs and teases you, then tells you to play it - she wants to see what kind of weird stuff you jack off to. You're reluctant but she tells you she won't leave you alone until she's seen it, so you put it back on and your sister settles down to watch it with you, poking fun at the story line and insisting that she finds it more ridiculous than hot. She teases you, asking if it's weird having her there while there's porn on, and saying it's your own fault for taking such a risk and watching it in the living room. You hope she'll get bored and go to bed soon but in fact she seems more and more engrossed as it goes on, and her mocking comments become less frequent as she admits that the actors are really hot, to be fair, and that the action is pretty sexy... After a while you notice her quietly and sneakily trying to caress herself through her pyjamas without you noticing; tweaking her nipples and running her hands over her thighs and panties. She notices you watching and stops, embarrassed, but soon starts again, unable to help it. You're half watching the porn now and half focussing on your sister, amazed as you see her pull her panties down slightly and start rubbing her pussy as she watches the screen. You can't help but rub your cock a little through your shorts now, and though you try to be discrete, your sister notices - but to your surprise, she tells you it's fine, you should just act like she's not there. You're a bit nervous but you decide to take her at her word and start stroking your cock properly, watching as your sister plays with her pussy more and more until she suddenly strips off her clothes completely, daring you to say anything. You keep quiet and she goes back to touching herself passionately now, completely naked on the couch next to you as you jerk off. She seems really into the porn now and comments frequently on what she's watching, seeming amazed and turned on by the action. When the guy cums on screen it sets her off, and she cums hard next to you; now completely unfazed by being right next to her brother! It's so hot watching her cum that you can't hold your own orgasm in any longer, and your sister watches in fascination as your cock spurts everywhere!
